<p>A method for preparing a microbial deodorizing agent comprising selecting an autotrophic purple sulphur bacteria from Allochromatium palmeri, Ectothiorhodosinus mongolicus, Halochromatium roseum, or a combination thereof, culturing at pH 6.0-7.0 at 43-45oC for 190-210 hours under light of 5000 Lux or higher, sterilizing by boiling the culture at 99oC for 5 minutes, purifying, stabilizing for 48-60 hours without feeding, filtering and harvesting. The microbial deodorizer is effective for removing odorous emissions attributed to ammonia, trimethylamine, formaldehyde, and hydrogen sulfide and is safe to the body and the environment including air and water.</p> |
